HATOHi-GOVER AND BATTING-DOWN CLAMP;

Application filed January 7, i919,iSeria1 No. 270,042. Renewed November 19, 1920. Serial No. 425,289.

T 0 alt whom it'ma/g concern Be it known thatlI, JOHN Pn'rERsoN,; a .ul i a i v SLIbJGCl; of the King 0t Sweden, and a: resident of Ashtabu-la, in? the county of Ashta bul'a and Stateof Ohio, have invented" new and improved Hatch-Covers and Batting Down Clamps, of which the' following, is a.

cover may be quickly" applied and removed" with'out'injury and sub'stantiall'y'in any kind of weather;

Another object in view is to provide a cover with: a plurality of slidingfsections together with clamping means" tor'clampi-n'g the covering t'arp'aulin or other covering sheet in place thereover.

A still further object ofth'e invention is to provide a series of pivotally mounted clamps along the edges and the ends of a hatch for clamping the covering over the hatch;

In the accompanying drawings:

Figure l is a top plan view of part of a deck of a ship showing a hatch withan improved cover and clampingrmeans therefor arranged in operative position-L 2 is a fragmentary side viewof the structure shown in Fig; 1..

Fig. 3 is a longitudinal vertical section through the structureshown in Fig. l, the same being'taken on line 3-3.

F ig. 4: is a transverse sectionalview through Fig. l on line 44, the same being on an enlarged scale.

Referring to the accompanying drawings by numerals 1 indicates the; deck of a ship of any desiredkind which is provided with a coaming 2 of substantially the usual 'con structionexcept thatit is provided with a depression or groove 3 asshown in Fig. 4 formed with an extension 4 projecting above coaming 2. The extension 4 has a depending plate 5 connected thereto or formed integral therewith, which is the case when metal is used. The bottom part of plate 5 is riveted or otherwise rigidly secured to the bottom of the coaming, as for instance by the same rivets 6 that secure the brackets 7 8 and also the edges of the covering canvas or tarpaulin 9. From Figs. 3 and 4 it will Specification of LettersPatent.

be seen that the plates 8 rest on the top edges 10 and 11 of the coaming 2 and may and hook 123 is a second hook 14. This hook, as'well as hook 13' extends for thefull length of the plate and interlocks with the hooks of adjacent plates; The central plates '8, how ever, are provided with the depending flanges 12, but not with the hooks 13', though anoverlapping extension 15 is pro videdas" shown in F ig'. 3. tral plates is provided with a pivotally mounted link 16' overlapping the post 17 on the opposite plate, said post being adapted to receive a pin 01- other locking means whereby the plates are locked in their extended" position. After the plates have been arranged in their extended position as shown in 3 the canvas 9' placed in position and the edges clamped as shown more particularly in Figs; 3 and 4!. in order to prevent accidental movement of the various plates 8 they are not' only locked to getherat the center, but the, end plates 8 are each provided with an upper webl8 aiida lower web 19, the webs 19"over'lapping' the ends of the hatch 2 while the upper webs 18 accommodate the canvas 9. After'the plates 8have'been moved across the coaming so as to completely cover the same as'shown in 3, the canvas 9 is placed in position so that the edges will overlap the c'oaming and then the various clamps 20 are moved to their clamping position shown particu larly in Figs; 3 and 4;

It will be evident that any desired number of clamps may be provided along" the sides of the coaiming and also along the ends. Each of these clamps is provided with a pair-of locking levers 21 having an extension 22 for accommodating the pin 23 extending through the hook end 24 of the various clamping members 20. The end, or rather the edge, opposite the hook 24; is turned over as at 25 so as to press the canvas against the extension 4; or against the webs 18 without cutting the same. Each of the hooks 20 is also provided with a cushion member 26 which may be rubber, which is pressed against the canvas 9 as shown in Fig. 4 when the clamps are in a locked position, which provides an absolutely water One of the cen tight clamping arrangement as well as an effective means for holding the canvas or tarpaulin and the covering formed by memhere 8 in proper position. Each of the levers 21 is pivotally mounted on a bracket 7 arranged with a somewhat rounded upper end for accommodating the locking link 27 pivotally mounted on the clamp 20. After the lever 21 has been moved to its upper closed position for operating the clamp 20 link 27 is moved downwardly to the position shown in Fig. 4f whereupon the members are locked against accidental disengagement. If desired a lever or a socket wrench 28 could be used for operating the lever 21 where the circumstances demand such a device, as for instance where the hatch is large and the parts are heavy.

In operation when the parts are all as to secure access to the hatch without removing the entire hatch cover. If desired the remaining clamps may be removed and the complete hatch cover removed. To replace the covering the covering plates 8 are pulled toward the center of the hatch and the parts connected together as shown in Figs. 1 and 3 after which the canvas is placed in position and the various clamps 2O moved to their clamped or locked position. This may be done quickly and easily as all of the clamping members or looking members are constantly in position on the upper part of the hatch so that the only thing necessary to bring to the hatch is the canvas covering 9 which may be kept at any convenient point. Under some circumstances this cover may be eliminated and in cases of this kind the hatch cover may be even more quickly ap plied and removed and held in position when applied. It will be observed from Fig. 1 that there is a space between the end clamps 20 on each side of the cover and the end clamps 20 and 20", said openings 29 permitting water to freely flow off of the canvas cover in case of rain.

What I claim is:

1. A hatch and cover comprising a coaming adapted to fit on the deck of a ship, a projection extending around the coaming and above the same, the upper edge of the projection being spaced from the coaming, a collapsible covering member arranged on said coaming, a flexible covering member overlapping said projection, a clamp engaging said flexible covering member for clamping the same to said projection on opposite faces thereof, and means for locking the clamping member in place.

2. A hatch and cover comprising a coaming fitted to the deck of a vessel formed with a groove extending around the upper edge, the material forming the lower part of the groove extending upwardly at an angle to said coaming forming a projecting flange, a depending plate connected to said flange extending downwardly at the same angle as the flange, means for securing the lower part of said plate to said coaming, a covering structure for the coaming resting thereon, and a flexible covering structure overlapping said flange, and a clamping mem ber pressing said flexible member against said flange and said plate.

3. A hatch and cover comprising a coaming formed with means providing a groove exteriorly of the coaming, the outer walls of the material forming the groove extending above the ooaming, a metal covering member for the coaming resting on the upper edge thereof formed of a plurality of plates having interlocking hook edges and reinforcing flanges, means for holding said plates in an extended position for covering said coaming and clamping means arranged around the coaming for clamping said plates against the coaming.
